...and that's what I'm on about. Simply making the orbit lines have a perspective would sort this. currently the orbit lines are nothing more than consistently solid single pixel width lines. would adding an in-game option to turn on 3D orbit lines be something worth while? I think so. nothing elaborate, either orbit lines that are slightly thicker on the 'closer to you' side and thinner on the far side, or perhaps a gradation filter (brighter closer to you, darker further away)
I've been thinking of mentioning exactly this for ages, kudos!
The optical illusion from far away, where you can't tell whether you're above or below the plane of the orbit, has always driven me slightly insane. As you say, slightly thicker or brighter on the closer side would be great.
As it is, I usually fly well below (or above, can't tell which) the plane, and when I know, I turn to approach at right angles to the orbit plane. A bit naff, but it works.

I would like this too but I'm afraid it's an optimization issue. Calculating hidden lines which would be needed for your simple sounding "simple graduation of the luminosity of the line, brighter would be closer, dimmer would be further away") doesn't come for free. If you take into account that some systems are full of orbital lines then that's probably not quite as trivial as you might think.
Even doing it just for the orbit line for the orbit your targeted body is in would be a big improvement on what we have.
If you're not going there, it doesn't matter so much.

Arrow always shows up in the closest orbit position.
Arrow points towards the orbit direction of the station/body
Not bad at all, though it could get lost in the background quite easily. Might well do the job. +1
